Your personal desktop companion

A little dog with a big personality.

Spike talks with you, remembers what you tell him, keeps your alarms and teases you just enough. He lives on your Windows PC today, comes with you on your phone, and is getting a body of his own.

Explore it yourself
Meet Spike

Cheeky when you're fine. Gentle when you're not.

He is a character, not a chatbot. He jokes, he roasts, he notices when you've had a long day, and his friend Spicy the cat is one click away.

  • Talk or type. Press Space and talk, or just start typing.
  • He remembers. Your tea, your cat's name, Friday's exam. Forget anything with a click.
  • Alarms with attitude. Yips, then barks, then jokes until you're up.
  • Yours to design. Every feature, colour and size in the Face Studio.
Everything he does
The Face Studio in Spike for Windows: a live preview of his face with moods, starting faces and save slots
The robot

One face, and a tuft of fur that hides his camera.

The screen draws his eyes, nose and mouth. Above it, a little caramel cowlick in the middle of his forehead hides the camera lens. It is his signature.

Private by design

His brain lives on your computer.

What Spike remembers, your alarms and your settings stay on your own machine. There is no account to make and nothing to sign up for.

  • No account, no ads, no tracking. SpaceZ runs no servers for the app and collects nothing.
  • Your voice stays home. Speech is turned into words on your computer and never recorded.
  • Your key, your choice. To think and speak he uses Google's Gemini with your own free key, and only the words of your chat go there.
  • Forget anything. See everything he remembers, and erase one thing or all of it.
